Its a activity tracker that also tracks calories burned, the water you drink, your heart rate etc. I bought a fitbit before this one came in the mail. so I never used this one. It has just been sitting around. You can read about it at their website: https://healbe.com/us/
It does display the time too. Here is what the manual says: TIME: Current time POWER: Percentage of battery life remaining PULSE: Your current heart rate KCAL: The balance of your consumed and burned calories KM / MILES: Distance traveled today STEPS: Amount of steps today WATER: Hydration Level
